Title: Oil diffusion pump
Inventor: SHIMIZU MASAYUKI
IPC: F04F9/00
Filed: 1981-07-22
Abstract: PURPOSE:To make it possible to eliminate the electrical leak of an oil diffusion pump by inserting an electrical insulating material between the base of an oil diffusion pump body and the top of an electrical insulator. CONSTITUTION:The outer periphery of an insulator 3 is made higher by DELTAl than the inside surface of it and only this high surface contacts with the base 1 of an oil diffusion pump body in order to provide a space 9 between the base 1 of the pump body and the insulator 3. As the result of this situation, the top of the insulator 3 inside a stacked iron powder 4 does not touch the pump body even if a heater 2 is heated, and the pump body 7 and insulator 3 are closely contacted with each other, so that resistance between the heater and grounding is not reduced, an the electric leak of an oil diffusion pump can be eliminated.

Inventor: SHIMODA MAKOTO
IPC: B03C3/155
Filed: 1980-08-21
Abstract: PURPOSE:To collect dust effectively up to submicron grains by installing a grain coagulator equipped with a discharging electrode and an adhesive member whose surface is covered with ciliation, to electrostatic precipitator. CONSTITUTION:A discharging electrode 4 and a grain coagulator equipped with a dust collecting part having an adhesive member whose surface is coverted with a lot of ciliation are installed to the front stage of an electrostatic precipitator so as to oppose each other.

Title: Scanning method of electron beam
Inventor: FUKUDA HISASHI
IPC: H01L21/027
Filed: 1978-09-14
Abstract: PURPOSE: To scan with an electron beam a limited section of a substrate for use in producing a super-LSI, by staggering a scanning starting point backwardly with respect to the scanning direction by a distance corresponding to the time by which the supply of an electric current is delayed, or without irradiating an electron beam initially up to a proper scanning starting point, whereby a uniformly exposed substrate can be obtained.  
     CONSTITUTION: An Si substrate having an oxide film thereon is coated with a resist, and this limited section is scanned with an electron beam. At this time, a scanning starting point is staggered backwardly with respect to the scanning direction by a distance a corresponding to the time by which the supply of an electric current is delayed so that an electron beam is not irradiated initially up to a proper scanning starting point. This prevents that portion of the substrate which is close to the scanning starting point from being swollen owing to no over-exposure at the mentioned portion of the substrate. Namely, the substrate is uniformly exposed so that it has no over-exposed portions.

Title: Liquid fuel combustion device
Inventor: KONAKAWA KATSUZOU
IPC: F23D3/18
Filed: 1983-06-24
Abstract: PURPOSE:To perform gentle motion even during rapid control, to normally maintain excellent combustion properties, and to enlarge a practical combustion variable range, by a method wherein a variable means, such as dampers, which varies the area of a combustion gas passage, is held through the medium of a material having the high coefficient of thermal expansion. CONSTITUTION:A resistance plate 19, sized to be larger than a main combustion gas passage 17, is located above a partition 16, and a shaft 20, having the one end secured to the partition 19, is vertically movably mounted in a manner to extend through approximately the center of an inner flame cylinder 3. As a result, the disc-shaped resistance plate 19 varies the main combustion gas passage 17 from full opening to full closing, and an auxiliary combustion gas passage 18 is normally opened irrespective of the resistance plate 19. The upper part of a shaft 20 consists of a shaft 21 formed by a material (Zn, Al, etc.), having the high coefficient of thermal expansion, a material, such as bimetal type shape memory alloy, which is expandable due to a temperature change. The shaft 21, expanded by a high temperature during maximum combustion, is prevented from closing the main exhaust gas passage 17 even during rapid control of blockade of the main exhaust gas passage by means of the resistance plate 19.

Filed: 1989-05-08
Abstract: PURPOSE:To prevent the rupture of a system due to the abnormality of the side of an output by detecting an overcurrent and stopping the input of a power source into an oscillating circuit. CONSTITUTION:When a DC voltage is supplied between terminals +VIN, -VIN, an oscillating circuit 1 outputs an AC voltage. The AC voltage is transformed by a transformer 2 and is converted into a DC voltage in a rectifying circuit 3, then, is stabilized by a constant voltage circuit 4 and, thereafter, is supplied to a load. When an overcurrent is conducted through the side of an output load, an overcurrent detecting circuit 5 outputs an overcurrent detecting signal to give it to a latch circuit 7 through an OR circuit 11 while the latch circuit 7 latches the signal and provides the circuit with a signal to put a transistor 8 ON. In this case, a circuit 6 stops the supply of the DC voltage to the circuit 1 and a light emitting element 9 issues an alarm. When an oscillating element 10 is provided, alarm sound may be generated.

Title: Semiconductor memory circuit
Inventor: TERAYAMA KAZUYOSHI
IPC: G11C11/413
Filed: 1991-05-21
Abstract: PURPOSE:To prevent a multiselect condition where a column selecting switch is nonselectively kept open by a nonsynchronous noise signal. CONSTITUTION:When a column decoder is in an inactivated condition, an NMOS transistor 3 is turned on and a node A becomes an 'L' level. Thus, a PMOS transistor 2 is turned on as well and since an NMOS transistor 4 is turned off, a node B becomes 'L' level and the column selecting switch constituted of NMOS transistors 5 and 6 is kept closed. When the column decoder is in an activated condition, since a control signal 102 is at an 'L' level, the existence of the transistor 3 is ignored during a circuit operation. Since the node A is not changed and kept at an 'H' level at a nonselective column decoder, the node B is kept at an 't' level. Thus, the column selective switch constituted of the transistors 5 and 6 is kept closed, a route directly connected to the column selecting switch does not exist even when a nonsynchronous noise signal is generated for a grounding conductor and thus, the generation of the multiselect condition is prevented.

Abstract: PURPOSE:To know a variation of a color at a glance by displaying simultaneously a coordinate for showing a color of an object to be measured to light whose wavelength is different from each other, on a chromaticity diagram. CONSTITUTION:The titled device is constituted of a CPU, a color measuring device, a CRT display device, etc. First of all, a standard sample and an object to be measured are measured with respect to its color by a color measuring device, and its L, (a) and (b) coordinate values are written in a RAM.

Title: Digital/analog conversion circuit
Inventor: SHIDA FUMIO
IPC: H03M1/80
Filed: 1988-05-11
Abstract: PURPOSE:To add optional offset voltage to analog output voltage through the use of a few element lines by combining a weighted resistor and a single grounded base transistor (TR). CONSTITUTION:An N-bits-quantized digital signal is inputted from digital input terminals 101-10N (N is integer), and weighted resistors 111-11N are determined in their resistance ratio according to the weight of an input signal. Because the emitter potential of the TR 130 can be considered to be at a fixed position independently of the magnitude of an emitter current as base potential is fixed, current values to flow in the weighted resistors 111-11N having been weighted are inversely proportional to respective resistance values. By converting the collector current of this TR 130 by a load resistor 132, a D/A converting operation is attained. Further, by varying the magnitude of a variable resistor 135 connected to an emitter, the emitter current of the TR 130 is varied, and by varying a voltage drop in the load resistor 132, the offset potential can be given to a D/A converted output signal.
